What conditions must be met for a dead ball to be made live?

• A. The pitcher has engaged the pitcher's plate while holding the ball in a legal pitching position.
• B. The batter and the catcher are in their respective boxes.
• C. The umpire calls 'Play' and gives the appropriate signal.
• D. All of the above.

Answer: (D)

In this rule set, a dead ball becomes live only when the game is officially ready to start the play. The pitcher must be prepared at the pitcher's plate in a legal pitching position, showing he’s ready to deliver. The batter and catcher must be in their boxes, ready for the pitch. And the umpire must call “Play” and give the appropriate signal to start the action. If any of these conditions isn’t met, the ball stays dead. Therefore, all of those conditions together are required for the ball to be live.
